reacts with the gold(I) hydride (IPr)AuH under insertion
to give the hydroperoxide (IPr)AuOOH, a long-postulated reaction in
gold catalysis and the first demonstration of O2 activation
by Au–H in a well-defined system. Subsequent condensation gave
the peroxide (IPr)Au–OO–Au(IPr) (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene).
The reaction kinetics are reported, as well as the reactivity of Au(I)
hydrides with radical scavengers.
